I built this one a few years ago, has served me well. A medium sized car will fit on it too.

Camper frames pretty thin light stuff. Maybe a real old one is better? I think a smaller trailer for say two ATV's might work, but thinking kind of light for four and that length. I think the camper structure itself was part of the strength factor when these were built. To keep lighter, use good outdoor 3/4" plywood, tongue and groove, like the lawn sheds made now days use for floors. Won't last forever, but should last long time and be lighter than any 2 x ? material.
I'm quickly coming to that realization,, 4 quads are going to be a bit much weight wise at a 3K capacity. 2 or 3 are going to be the limit as long as I can keep the trailer weight under 1K. Its ok as I can still put one in the box of the truck. I'll keep that plywood in mind for the floor covering, I suppose quads really don't need 2x lumber.

With my trailer (above), the 2 side rails were quite hefty while the cross braces were just thin angle iron. As you can see in the 2nd pic, I added quite a few heavier cross pieces, Then used 2x10 pressure treated as floor boards.

I would add more crossmembers currently they look like 3 or 4ft centers which would not be enough for much of anything. I have been thinking of the concept of point loading, as a camper the load would have been distributed over the whole frame whereas hauling quads the load would be placed at just the 4 points where the tires meet the bed, since this trailer would be for a specific purpose I would add structure to compensate for the point loads. All my quads are class 1, 48" so just 2x where the tires run would suffice and fill in the rest with 5/4, expanded metal or nothing. I suppose I could lose one of the axles to get the unlaiden weight down and since we would only have a capacity of 3K, I am thinking the best option would be to keep the braked axle?

I had one exactly like what poncho62 started with. I just bolted down rough-cut 8/4 oak from a sawmill as a deck, and hauled everything from farm tractors, skidsteers and cars to rolls of hay on it. It had main rails of 6"x3" channel, and 5" wide formed cross rails. My FIL still hauls 7000lbs + of hay on it regularly.
